RP and RPM Network Port indefinite object instance (#146)

Browse Source 
* RP and RPM Network Port indefinite object instance

Added ReadProperty and ReadPropertyMultiple handling for
Network Port object indefinite object instance 4194303.

* Add network port object to some examples

* Fix stm32f10x build

* Fix Endian order of network port IP UDP port

* Add network port object to BDK Makefile

* Add network port object header to BDK device.c

* fix BDK and AT91SAM7S port builds
